The printer installer can be used to automatically install network printers to a user's profile, for example.

Essentially, the program only needs to be run once per user for the printers to then stay a part of that user's profile (thus making it great to be used with Startup Manager's 'Run Once' option - another Mellow Marsh software product), but it can quite happily run every time someone logs on - it will simply appear for a second or two on every subsequent run, as the drives will only be installed upon the first execution.
